[resolved] Website not showing fine on Mozilla (5 posts)

I have made some changes in the width of the page template in my CSS style sheet from 67.7% to 100% to make my content appear across the page with just enough margin on either sides of the website pages.

After doing the same, my site is working fine only on Chrome and I.E and not on MOZILLA where the content and pictures are showing up as thumbnails vertically. However when i reload the page it appears fine going back to their original size.

Can anyone help me with this please, even the site favicon shows well on Chrome appears broken in Mozzila.
